METAL ROOFING.

SPECIFICATION forming part of Letters Patent No. 502,552, dated August 1, 1893.

Application filed March 21, 1893. Serial No. 467,030. (No model.) Patented in Belgium February 20, 1884, No. 64,2213, and in France October 29,1884, N0.165,0'79.

To all whom it may concern:

Be it known that I, BENOIT BAILLOT DE- TOMBAY, of Ohne, Belgium, have invented new and useful Improvements in Metal Roofing, (for which I have obtained Letters Patent in France, dated October 29, 1884, No. 165,079, and in Belgium, No. 64,221 B, dated February 20, 1884,) of which the following is afull, clear, and exact description.

My invention relates to improvements in metal roofing which is preferably made of zinc, but may be made of any sheet metal, and the object of my invention is to produce a roof of this character which is durable and inexpensive, which may be rapidly applied to any kind of a wall, whether vertical or of any degree of pitch, which is attached in such away that all the fastening rivets or nails are covered, which has the sheets jointed in. a manner to render the joints absolutely wind and water-tight, which may be made very ornamental,which is extremely strong, and which may be very rapidly applied to a building.

To these ends, my invention consists in core, tain features of construction and combinations of parts, which will be hereinafter described and claimed. I

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a broken perspective view of several overlapping sheets of roofing embodying my invention, the view illustrating the manner in which the sheets are secured together and to a roof. Fig. 2 is a cross section on the line 22 in Fig. 1. Fig. 3 is an enlarged cross section on the line 33 in Fig. 1, and illustrates the manner in which the sheets are locked together. Fig. 4 is a detail sectional view on the line 4-4 in Fig. 1, showing the manner of fastening the sheets to a wall. Fig. 5 is a detail sectional view on the line 55 in Fig. 6, and illustrates one of the rib joints which prevents lateral movement of the sheets. Fig. 6 is a sectional view on the line 6-6 in Fig. 1, and shows in elevation the overlapping ribs of two sheets; and Fig. 7 is a broken perspective view of the top of a gable roof, and shows the'manner of covering and protecting the ridge-pole.

The roofing is made up in sheets 10, which are provided with parallel ribs 11, formed by pressing out the metal of the sheets, these ribs extending entirely across the sheets and being pressed preferably in groups of two each, as illustrated in Figs. 1 and 2, although they may be differently spaced if desired. The sheets are turned up slightly at one edge, as shown at 12, and down slightly at the opposite edge, as shown at 13 in Fig. 4t,.these turned portions extending at right angles to the ribs, and this arrangement causes the overlapping portions of adjacent ribs to fit very snugly, the bent or turned part of one sheet abutting with the other, and in this way leakage through capillary action is prevented.

The sheets are fastened to a Wall by nails or equivalent devices 14, which are driven through countersunk portions 15 in the sheets, so that the heads of the nails are thus kept out of contact with the'sheet above, and the nails are driven near the upper edge of a sheet so as to becovered by the'overlapping portion of the sheet above.

On the inner side of the rib l1, nextto one edge of each sheet, is a tongue 16, which is soldered or otherwise fastened to the rib and which extends upward parallel with the wall of the rib, and on the opposite edge of the sheet and on the exterior surface of the outer rib is a downwardly-extending tongue 17, and consequently when two ribs are placed together with their side edges overlapping, the rib of one closingoverthe rib of the other, the tongue 17 will rest in the tongue 16,that is,they willinterlock, as shown in Fig. 3, and the interlocking tongues will prevent the sheets from lifting from the wall, and. the strain on the tongues will be in a nearly edgewise direction, so that they are able to withstand any strain to which they are subjected.

The sheet 10 on one edge terminates in a half rib 11, which is inclined outward and adapted to be held within a rib 11 of the next adjacent sheet, as shown in Fig. 3. To prevent any lateral or shifting movement of the sheets, the ribs 11 of each sheet are provided at their lower ends and inner sides with tongues 18, which open toward the lower end of the sheets, and consequently these tongues are adapted to fit over the upper edges of the ribs on the next sheet below, as shown clearly in Figs. 1, 5 and 6, and the tongues 16 and 17, by engaging each other, lock the whole series of sheets together so as to form practically a continuous metal plate which cannot slip laterally, and which is prevented from lifting or bulging from the wall.

It will be noticed that these sheets may be applied to a wall of any angle, whether it be a pitch roof or a vertical wall, and it will also be understood that the sheets may be bent to fit any peculiar portion of a wall.

In Fig. 7,1 have illustrated the manner in which the meeting point of two pitch roofs may be covered, and here theroofs are covered by plates 10, arranged exactly as described above, and these plates extend up to a point above the ridgepole and the space between the plates on the opposite roof is covered by plates 10, one of which has a flange 20, adapted to overlap the upper edge of the op posite plate so as to form a tight joint. These plates 10 have at their lower edges angular flanges 21 and 22, which hold them a proper distance from the roof, the flanges 21 corresponding in height to the height of the ribs 11, and the flanges 22 being adapted to rest flatwise on the plates or sheets 10.

The flanges 21 and 22 are cut away, as shown at 23, to receive the ribs 11 of the sheets 10, so that the cover plates or sheets 10 may fit snugly on the roof. 7

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A roofing sheet having a series of ribs and provided on the inner side of a rib near one edge of the sheet with a tongue extending upwardly parallel with the wall of the rib and on the exterior surface of a rib on the opposite edge of the sheet with a tongue extending downwardly parallel with the wall of the rib, whereby the tongues of the sheets will interlock to prevent the sheets from being lifted from the wall or roof, substantially as described.

2. In metal roofing, the roofing sheet having parallel hollow ribs thereon, an upwardly-inclined tongue on the inner surface of a rib near one edge of the sheet, a downwardly-inclined tongue on the exterior surface of a rib near the opposite edge of the sheet, the tongue of one sheet being adapted to engage the tongue of an adjacent sheet, and tongues on the inner surfaces of the metal ribs of the sheet, the tongues being arranged near one edge of the sheet so as to receive the edges of the ribs on the sheet below, substantially as described.
